We had a chance to chat with some ARM chaps at the Mobile World Congress and we saw a nice dual-core vs single-core demo. Apart from that, one of the chaps confirmed that A15 CPUs are waiting for the new 28nm process and other sources have told us to expect some tape outs and initial products later this year.

Nvidia is one of the prime candidates to have its Tegra 3 out before the new year of 2012, but this depends of TSMCs ability to transition to the new process.

Since mobile devices are Linux based and they do a lot of things at the same time, ARM believes that after two cores there is room for four cores and possibly even more down the road.
